ATLAS21bidw (AT2021yja): discovery of a candidate SN in NGC 1325 (22 Mpc)
Abstract
Here we report the ATLAS discovery of the transient ATLAS21bidw (AT2021yja) in galaxy NGC 1325 at magnitude m_c = 15.33 +/- 0.01. At a distance of 22 Mpc (redshift independent, from NED), the transient was discovered on MJD = 59465.55 (2021-09-08.55) with an absolute magnitude of M = -16.42 +/- 0.01. The last non-detection through forced photometry was on MJD = 59463.48. Spectroscopic classification is encouraged.
